Description

Automatically controlling wet paper plastic molding machine, method for automatically controlling wet paper plastic molding, and the same Paper and plastic products prepared by dynamic control of wet paper plastic molding method

The invention relates to the technical field of automatic control of wet paper pulp molding, in particular to an automatic control of wet paper plastic molding machine, a method of automatic control of wet paper plastic molding, and a paper plastic prepared by the method of automatic control of wet paper plastic molding. product.

At present, the inner packaging or outer packaging of 3C products is gradually adopting a wet pulp molding technology. The principle is to use mold components to quickly and massively integrate the pulp into a three-dimensional wet pulp molding product. For example, the new type patent publication No. M516615 of the Republic of China discloses the conventional wet paper plastic molding machine 1 shown in Fig. 1. Its main structure includes: a single pulp fishing operation area 20, and a first lower mold 23 A slurry tank 21 collects the first slurry 100 to form a layer of wet embryos on the upper surface of the first lower mold 23, and then the first lower mold 23 and the corresponding first upper mold 22 of the wet embryos Pressing the mold up and down to perform a first pre-pressing step to form a wet embryo; a first hot-press forming operation area 30 is adjacent to the first pulping operation area 20, and a second upper mold 31 and a The corresponding second lower mold 32 heats and compresses the wet embryo to perform a pre-heat pressing step, thereby forming a second semi-finished product; a second hot-press forming operation area 40 is adjacent to the first hot-press. The molding operation area 30 uses a third upper mold 41 and a corresponding third lower mold 42. The second semi-finished product 103 is heated and press-molded to perform a hot-press molding step, thereby forming a third semi-finished product; and a cutting operation area 50 adjacent to the second hot-press molding operation area 40, using at least one knife The mold 51 is used for cutting the third semi-finished product to form a paper-plastic product.

However, when a paper-plastic product with a double-layer shaped paper cross-section structure needs to be manufactured, the upper paper-plastic structure and the upper-layer paper-plastic structure superimposed on each other in the paper-plastic product with the double-layer cross-section and The overall size of the lower-layer paper-plastic structure is different. If the conventional wet paper-plastic molding machine 1 is used to manufacture such a paper-plastic product with a double-layer paper-plastic cross-section structure, one of the following problems may occur:

(1) Since the first pulping operation area 20 of the conventional wet paper-plastic molding machine 1 described above can only accommodate a working space of one mold assembly, it is necessary to separately install two sets of mold assemblies of different sizes and The two upper and lower layers of the paper-plastic structure are respectively shaped during periods of non-overlapping. For example, please refer to FIG. 1B, which is a working sequence diagram of each operation area of the conventional wet paper molding machine 1 shown in FIG. 1. First, only the first pulping operation area 20 is installed. A first set of mold components 22, 23 and set the first set of mold components 22, 23 to complete each of the first duty cycle T1 (including the execution of the first pulping and pre-pressing steps) The molding of the lower-layer paper-plastic structure; after completing the molding of each lower-layer paper-plastic structure, it takes additional time to manually replace (plus adjust) the first pulping operation area 20 into another one. The second set of mold assemblies of different sizes and the second set of mold assemblies are additionally set to complete the molding of each of the lower paper-plastic structures in each second work cycle T2 (including the execution of the second pulp fishing and pre-pressing steps). type. This application will make it impossible for the first work cycle T1 and the second work cycle T2 to overlap, which will lengthen the overall work time; after that, the two upper and lower paper-plastic structures are manually separated. Move from this first pulping operation area 20 to the next hot press forming operation area 40 or 40 and overlap each other (the required operation time is T3), and then use the third set of mold assemblies 41, 42 to heat press the upper and lower layers of the paper-plastic structure up and down (the required work time is T4) to form a semi-finished product. However, this is quite time-consuming and labor-intensive, which will be detrimental to the work efficiency required for mass production of paper and plastic products by automated machines.

(2) In another application of the conventional wet paper plastic molding machine 1, the first pulping operation area 20 uses the same set of mold components 22 and 23 to respectively shape the two upper and lower paper and plastic structures. For example, the same set of mold components 22, 23 completes the molding of the lower paper-plastic structure in a first work cycle T1 (including the execution of the first pulping and pre-pressing steps); after completing the lower paper-plastic structure After the molding, the same mold assembly 22, 23 then completes the molding of the lower paper-plastic structure in a second work cycle T2 (including the execution of the second pulp fishing and pre-pressing steps), where the first work There is still no overlapping period between the cycle T1 and the second work cycle T2, which still lengthens the operating time and is not conducive to the work efficiency required for the automated machine to mass produce paper and plastic products; at the same time, the same mold assembly 22 is used. The size of 23 cannot accurately shape the different sizes of the two upper and lower paper-plastic structures respectively.
